I did manage to copy the gameplay cd, but I forgot to check the options for the subchannel stuff, so I now have a cd that will autorun, install, but not play.

Oh well, now that I know how to do it correctly, I'm going to use it so I can have my kids play w/ me. I will of course only play on Battlenet w/ the one ACTUAL copy that I bought, but me and my kids are loving the lan game! Way cool that you can play your char in single player, then use him in the multiplayer!! Gotta love that!
